Abstract
Dans la présente invention, un courant d'hydrocarbure gazeux (10) est refroidi contre un premier réfrigérant et un second réfrigérant, pour produire un courant d'hydrocarbure liquéfié (20). Le premier réfrigérant subit un cycle dans un premier circuit de réfrigérant (100), comprenant une compression dans un premier train de compresseurs (110) comprenant un ou plusieurs premiers compresseurs sur un arbre de transmission commun (215). Le second réfrigérant subit un cycle dans un second circuit de réfrigérant (200), comprenant une compression dans un second train de compresseurs (210) comprenant un ou plusieurs seconds compresseurs sur ledit arbre de transmission commun (215). L'arbre de transmission commun (215) est entraîné avec une turbine à gaz unique (220). Un premier courant d'air d'admission (225) pour la combustion est refroidi contre un courant d'un liquide de refroidissement réfrigéré (320) puis est transféré à la turbine à gaz unique (220).
